Some more behaviors a visiting Martian anthropologist might find a bit odd:

Janet Jackson's breast seen on TV for a fraction of a second causes a huge outcry and a $500,000 fine for the network. Dead Iraqis shown lying in pools of blood with flies crawling on them during coverage of the invasion of Iraq is acceptable family television and stirs no reaction from the righteous save higher ratings (I saw this on CNN in the afternoon, i.e. when kids would be watching).

On the other hand, National Geographic can publish photos of naked Africans and Amazon tribes without stirring the slightest controversy. Only Western breasts are terrifying.

People taking advise on sexuality, child-rearing, marriage, etc. from celibate clergy whose only experience in the area (for those who have any experience at all) comes from molesting kids.

Permitting the use of mood-altering drugs that cause hundreds of thousands of deaths and other assorted mayhem each year (alcohol and tobacco) while throwing people in jail for using marijuana to cure nausea while they take chemotherapy, or just using it for fun. Then electing a President who used it--who perpetuates this status quo without volunteering to go to jail for his own publicly-admitted "crime."
